Q.2) Give reason. a) A map is more accurate than the globe. Ans) Map gives us accurate location, direction and information in detail about an area or country because it is drawn to scale. b) A verbal Scale is not as popular as a linear scale. Ans) Verbal scale does not give accurate measurement as it is expressed in words. E.g. I cm = 50 Km on ground. c) Pole star is useful in finding directions. Ans) it is always visible in the sky and points towards North direction. Q.3) Differentiate between. a) A map, sketch and plan Map: ➢ Shows a larger area ➢ Serve the purpose of finding the location of country, distance, direction etc ➢ Drawn on small or large scale Sketch: ➢ Rough drawing ➢ May not show all details ➢ Not drawn on scale Plan ➢ Shows a small area ➢ Serves only a limited purpose regarding township or a house ➢ Shows small area on large scale. b) Large Scale and Small Scale maps Large scale maps: ➢ Show a small area in great detail. e.g. Cadastral and Topographical map. Small Scale maps: ➢ Show large area in less detail and space e.g. Wall, atlas maps. c) Tributaries and Distributaries Tributaries: ➢ A stream or river that flows into a larger stream or main stream. ➢ It does not flow directly into a sea or ocean. Distributaries : ➢ A river or stream that branches off the main stream and flow away. ➢ Most often found in river deltas. d) Meander and Delta Meander ➢ The river moves and its course forms broad S shaped loops on curves. Delta ➢ Fan shaped alluvial deposit at the mouth of the river. e) Anticline and Syncline Anticline: ➢ Arched or upraised parts of the fold Syncline: ➢ Downward fold or an inverted anticline Q.4)(a) Why is a map more useful than a globe? Give two reasons? Ans)(i) It gives accurate location, direction and information in detail about an area or a country as it is drawn to scale. (ii)It is light in weight and convenient to carry. (b) Why is a verbal scale not accurate? Ans)In this method, the scale is expressed in words-e.g. 1 cm = 50 Km on the ground. This is not very popular as it is not accurate measurement. (c) What is meant by R.F.:1:50,000? Ans) It means that I cm on the map represents 50,000 cm on the ground. This is representative fraction = Distance on the map/ distance on the ground. (d) What are the advantages of drawing a map to scale? Ans) For accurate location, direction and information in detail about an area or a country of a map (e) Identify and draw the figure and label it. Ans) Meandering river (f) What is the significance of colours in map reading? Ans) Colors are important in conventional signs and symbols. They are universally accepted. Colours stand out from the map and provide identification to many features. They represent natural and manmade features of earth. (g) Name the intermediate dimensions? Ans) NW,NE,SW,SE (h) State any two ways used to measure distances. Ans) Verbal scale, linear scale. (i) What is the significance of symbols in maps? Ans) Symbols represent the features on the Earth’s surface. Natural and manmade features are depicted by symbol e.g. river, ponds, roads, trees, etc. These symbols are universally used by all. (j) What do you mean by origin of a river? Ans) The origin is called source of the river. It originates from a mountain or higher slope. (k) State two features of the middle course of a river?

CHAPTER -2 (Land forms) Q.1) Differentiate between. A) Old fold and young folds mountains. Old fold : ➢ They are lower with rounded peaks and gentle slopes. ➢ May be over 200 million year old Young folds ➢ They have rugged features like pointed peaks and steeper and deeper slopes. ➢ Generally 10 to 25 million years old. B) Rift valley and Block mountains. Rift valley : ➢ It is a lowland region that forms where earth’s tectonic plates move apart or rift. Block Mountains ➢ They are the result of faulting. When the earth’s crust cracks faulting takes place. C) Erosional Plains and depositional plains. Erosional Plains : ➢ They are formed as a result of erosion and weathering. ➢ Main agents are running water, ground water Depositional Plain ➢ They are formed by the deposition of sediments on a large scale. ➢ Main agents are the accumulation of silt by river D) Intermontane plateau and piedmont plateau Intermontane plateau : ➢ They are situated between two or more mountain ranges. They are the highest and most extensive type of plateaus. Piedmont Plateau ➢ They are surrounded by mountain ranges on one side and bounded by a plain or ocean on the opposite side. Answer in brief: Q.2) (a) How are fold mountain formed? Give two examples of fold mountains. Ans) They far formed when mountains which have been thrown into massive folds or ridges by the Earth’s movements. E.g. The Himalayas, Rockies. (b) State two characteristics of block mountains. Ans) Steep sided and flat topped mountains, steep slopes and smooth topography. (c) How are rift valleys formed? Give one example of rift valley. Ans) It is a lowland region that forms where earth’s tectonic plate move apart or rifts. e.g. The rift valley. (d) Compare life in the mountains and in the plains. Ans) Life in mountains are thinly populated regions due to difficulties of transport, shortage of level land, rigorous climate and thin soil cover but the plains are thickly populated because of fertile soil, fine climate easy for railways, roads and waterways. (e) What type of mountain is Mt. Kilimanjaro? Ans. Volcanic mountain. (f) Define structural plains? Ans) They are formed as a result of emergence of sea bottom near coast. They lie near the coast. Q.3) Give reasons. (a) Young fold mountains have high peaks. They are arc shaped constituted of sedimentary rocks, more rugged features like high, pointed peaks. (b) Tibetan plateau is surrounded by mountains: They are example of intermontane plateau. They are situated between two or more mountain ranges- between Himalayas Kunlun mountain. (c) Rift Valleys have steep sides: They are formed where earth’s tectonic plate rift, bounded by fault zone and separated by land masses. Inside question Answer: Q.1) Define landforms? Ans) The solid part of the earth’s surface is constituted by various physical features called landform e.g. mountains, valleys, plateaus and plains Q.2) Differentiate between Exogenic and Endogenic forces. Ans) The external forces that act on the earth’s surface like river, glacier, wind, waves and wear down the rocks over a long period of time are exogenic forces. The internal process that may be felt suddenly on the surface like earthquakes, volcanic or tidal activity. It may be slow or sudden movement. Q.3) Differentiate between Epeirogenic movement and orogenic movement.

  • Venezuela Location Geography Food
    Venezuela Location Venezuela, officially the Republic of Venezuela, is a republic (1995 est. pop. 21,005,000), 352,143 sq mi. (912,050 sq. km), in the northern part of South America. With the Caribbean Sea in the north, Venezuela has a coastline of 1,750 long. It is bordered on the south by Brazil, on the west and southwest by Colombia, and on the east by Guyana. Dependencies include Margarita Island, Tortuga Island, and many smaller island groups in the Caribbean. Caracas is the capital and also the largest city in Venezuela. Geography Venezuela, a third larger than Texas, occupies most of the northern coast of South America on the Caribbean Sea. Mountain systems break Venezuela into four distinct areas: (1) the Maracaibo lowlands; (2) the mountainous region in the north and northwest; (3) the Orinoco basin, with the llanos (vast grass-covered plains) on its northern border and great forest areas in the south and southeast, and (4) the Guiana Highlands, south of the Orinoco, accounting for nearly half the national territory. Food The food in Venezuela is generally easy and flavorful. Caracas, the capital of Venezuela, claims to have a greater variety of restaurants than any other South American city, and it would certainly be a pleasure to try and prove it, even if you failed. Venezuelan cooking has European, indigenous, and African roots – a heterodox cuisine formed over the centuries by immigrants. Some of the native dishes include: Page 1 of 7 - Pabellon - stewed and shredded meat accompanied by rice, black beans, and baban -Hallaca - a traditional Christmas dish.

  • Major Landforms and Their Economic Significance MODULE - 2 Changing Face of the Earth 7 Notes MAJOR LANDFORMS and THEIR ECONOMIC SIGNIFICANCE
    Major Landforms and their Economic Significance MODULE - 2 Changing face of the Earth 7 Notes MAJOR LANDFORMS AND THEIR ECONOMIC SIGNIFICANCE You have learnt in the previous lesson that the landforms found on the earth’s surface are the result of interplay between internal and external forces. The soft rocks are easily worn down by these forces. While the relatively harder rocks are not so easily worn down. Therefore, rocks have a great influence on the landforms developed in an area. The internal forces are perpetually elevating the earth’s surface and the external forces about which you will study in the next lessons are constantly wearing down such elevations to make ,the surface level. This is how various landforms are formed by constant action of agents of gradation. These landforms are not only the physical features of the earth’s surface but also the basis of human civilization. The major landforms found on the earth’s surface are mountains, plateaus and plains. In this lesson, we will study the major landforms of the earth and their economic importance for us. OBJECTIVES After studying this lesson you will be able to : differentiate among the three major landforms found on the earth’s surface; explain the process of formation of various landforms with the help of illustrations; classify mountains on the basis of their mode of formation; discuss the usefulness of mountains to man; list different types of plateaus and describe their economic significance; GEOGRAPHY 121 MODULE - 2 Major Landforms and their Economic Significance Changing face of the Earth enumerate major types of plains and explain their influence on human life; locate major mountains, plateaus and plains on the outline map of the world.

  • FRESH-WATER SHRIMPS (CRUSTACEA, DECAPODA, NATANTIA) of the ORINOCO BASIN and the VENEZUELAN GUAYANA Gilberto Rodriguez the Guaya
    JOURNAL OF CRUSTACEAN BIOLOGY, 2(3): 378-391, 1982 FRESH-WATER SHRIMPS (CRUSTACEA, DECAPODA, NATANTIA) OF THE ORINOCO BASIN AND THE VENEZUELAN GUAYANA Gilberto Rodriguez ABSTRACT Shrimps of the families Sergestidae and Palaemonidae collected in the Orinoco basin, the upper Cuyuni River, and the upper and lower Rio Negro, are dealt with in this paper. New records and comments are given for Acetes paraguayensis, Macrobrachium amazonicum, M. brasiliense, M. jelskii, M. nattered, M. surinamicum, and Palaemonetes carteri. Two new palaemonids are described: Macrobrachium cortezi, a form related to M. nattereri, from several localities in the Orinoco River and upper Rio Negro, and M. aracamuni, from an altitude of 680 m in the Cerro Aracamuni in the drainage area of the upper Rio Negro. Another previously undescribed species of Macrobrachium is recorded but not named due to the lack of mature males. The Guayana highland is an ancient land mass extending from the Amazon River to the Atlantic coast of South America and includes the Guianas and parts of Venezuela and Brazil. The Venezuelan Guayana comprises 41,300 km2 of territory, mostly above 400 m that separate the Orinoco from the Amazon basin and forms a formidable barrier to the dispersion of the fresh-water fauna of the lowlands. The hydrology of the zone is defined by the Orinoco River that bounds the area to the west and north and its tributaries that generally flow north or northwesterly. A smaller portion to the east is drained by the Cuyuni River. The Orinoco and the Amazon basins are connected through the Brazo Casiquiare, while the inundated savannah of Rupununi allows intermittent connections be­ tween the Branco and the Esequibo Rivers (Lowe-McConnell, 1964).

    GEOLOGY: N. M. FENNEMAN 17 PHYSIOGRAPHIC SUBDIVISION OF THE UNITED STATES By Nevin M. Fenneman DEPARTMENT OF GEOLOGY, UNIVERSITY OF CINCINNATI Communicated by W. M. Davis, November 24, 1916 Various attempts at subdivision of the United States into physio- graphic provinces have been made, beginning with- that of Powell.' The Association of American Geographers, recognizing the fundamental importance of this problem, appointed a committee in 1915 to prepare a suitable map of physiographic divisions. The committee consists of Messrs. M. R. Campbell and F. E. Matthes of the U. S. Geological Survey and Professors Eliot Blackwelder, D. W. Johnson, and Nevin M. Fenneman (chairman). The map herewith presented and the ac- companying table of divisions constitute the report of that committee. The same map on a larger scale (120 miles to the inch) will be found in Volume VI of the Annals of the Association of American Geographers, accompanying a paper by the writer on the Physiographic Divisions of the United States. In that paper are given the nature of the bound- ary lines and those characteristics of the several units which are believed to justify their recognition as such. Though the above-named com- mittee is not directly responsible for the statements there made, many of them represent the results of the committee's conferences. The paper as a whole is believed to represent fairly well the views of the committee, though in form the greater part of it is a revision of a former publication.2 The basis of division shown on this map, here reproduced, is physio- graphic or, as might be said in Europe, morphologic.

  • Ecological Risk Assessment of Wildland Fire-Fighting Chemicals: Long-Term Fire Retardants
    ECOLOGICAL RISK ASSESSMENT OF WILDLAND FIRE-FIGHTING CHEMICALS: LONG-TERM FIRE RETARDANTS Prepared for: Fire and Aviation Management & National Technology and Development Program U.S. Forest Service Missoula, MT By: Headquarters: 51 West 4th Avenue Denver, CO 80223 August 2020 Ecological Risk Assessment: Retardants August 2020 EXECUTIVE SUMMARY ECOLOGICAL RISK ASSESSMENT OF WILDLAND FIRE-FIGHTING CHEMICALS: LONG-TERM FIRE RETARDANTS August 2020 The U.S. Forest Service uses a variety of fire-fighting chemicals to aid in the suppression of fire in wildlands. These products can be categorized as long-term retardants, Class A foams, and water enhancers. This chemical toxicity risk assessment of the long-term retardants examined their potential impacts on terrestrial wildlife and aquatic species. Exposures from both planned and accidental releases were considered, including on-target drops to terrestrial areas, accidental or unavoidable drops across water bodies, and accidental spills to a stream during aerial or ground transport. This risk assessment evaluates the toxicological effects associated with chemical exposure, that is, the direct effects of chemical toxicity, using methodologies established by the U.S. Environmental Protection Agency. A risk assessment is different from and is only one component of a comprehensive impact assessment of all types of possible effects from an action on wildlife and the environment, including aircraft noise, cumulative impacts, habitat effects, and other direct or indirect effects. Consultation under Section 7 of the Endangered Species Act and environmental assessments or environmental impact statements pursuant to the National Environmental Policy Act consider chemical toxicity as well as other potential effects to make management decisions.

Establishing vegetation is a very effective means of stabilizing soil and reducing accelerated erosion. Vegetative measures can be characterized as temporary or permanent. Temporary measures are designed to provide short- term protection until permanent measures can be installed. Permanent measures are installed once construction is completed. It is important to remember that vegetative measures need to be combined with runoff and sediment control measures in order to be effective. Runoff and sediment control measures can be found in this handbook or in the California Stormwater Best Management Practice (BMP) Handbooks (available at www.casqa.org). Designers will need to consult with their local USDA Natural Resources Conservation Service Office for soils information and local departments of public works and/or transportation for specific hydrologic and hydraulic analysis procedures. -2­ Table of Contents Introduction................................................................................................................................... 2 Table of Contents .........................................................................................................................
